Electrical Characteristics
The average temperature coefficient of the reference input voltage, ∝ V
Where:
T
∝ V
Example: V
Note 6: The dynamic output impedance, r
When the device is programmed with two external resistors, R1 and R2, (see Figure 2 ), the dynamic output impedance of the overall circuit, r
